. Claims. (Cl. 160-176) This invention relates to improvements in Venetian blinds; and particularly to fixtures or brackets for engaging the top bars by which the blinds are mounted upon the frame or casing of a window or similar opening.

An object of the invention is to provide an improved type of supporting bracket for a blind of this type, preferably of sheet metal having the required outline and bent into final shape, with the parts of such design as to be readily assembled and quickly secured in place and formed to engage the top bar of the blind so as to support it in operative position and permit all the required adjustments.

A further object is to provide a bracket for each end of the top bar of the blind that is iriexpensive and simple in construction, and easy to produce in large quantities; as well as strong and durable and very efficient in use.

' These and other objects and advantages are explained in the following description taken with the accompanying drawings, whereon:

Figure 1 is a front or inside view of a Venetian blindhung in a window frame.

. Figure 2 is a view, partly in section, of one of the brackets'for the upper bar thereof.

Figure 3 is a front view of said bracket.

Figure '7 shows a detail.

Figures 8 and 9 are respectively a front and side view partly in section, of a modification of the bracket of Figure 4; and

Figure 10 shows a detail of a further modification.

. I use the numeral 1 to indicate the blind as a whole and 2 the window or other openingfin' casing or opening 2, or against the faces thereof lying approximately in the plane of the wall or partition containing the window opening. The I blind also comprises the slats B and a bottom rail 1 that are suspended from the top bar or rail 3 by means ofbands orstraps 6, of stout cloth or other material. Attached to one end of the bar 3 is a flexible operating element or cord 9 for rotating the bars and slats to adjust them so that the planes thereof can be turned towards vertical or. horizontal positions; and at the opposite extremity of the bar 3 is another cord [0 ing the blind, or letting it down. I

The length of the top bar can be adjusted, so that it can be utilized for openings of different sizes. It is made up of two channel-shaped metal sections l I and [2 with overturned edges as shown at l3 along the flanges thereof, as shown on section l2, which telescopes into the section II, having similar flanges. By pulling the section 12 out or pushing it in, the length of the bar 3 is varied accordingly. The two sections are secured in adjusted relation by means of notches in one edge l3 of the section I2, to receive a resilient catch fastened to the adjacent part of an edge of the section H, as illustrated in my copending application Serial No. 734,354 fora blind, filed of even date herewith, and now forfeited; The bent-' over edges are cut to form tongues I5 which are pressed down on the upper ends of the straps 8 to attach the straps to the bar 3, and these straps are also secured in the usual way to both edges of each slat 6 and the bottom bar 1.

The upper bar 3 has a trunnion or journal Ila. on the extremity of the section II, which is engaged by a socket or bearing formed by a pair of clips I! with concave inner faces on an angle plate l8 aflixed to another angle plate I 6, that is held by the plate l. The opposite extremity of the bar 3 has two flat projections 19, which serves as a key to rotate the bar 3. This key is received in a U-shaped hanger or rocker 20, having two separate upright projections 2|, each having a notch or recess 22 at its inner edge; and the key fits into these recesses. The hanger is perforated for rais- 5 to receive a stud 23 engaging a semi-circular slot 23 in another angle plate 16' that is held by the plate 5 and immovably mounted thereon. The rocker 20 is fixed to one end of a pivot stud 24- disposed in a bearing 25 on the plate l6','and carrying on its opposite end a grooved wheel 26. "The stud is fixed to this wheel and passes through theslot 23', thus connecting the rocker 20 and wheel 26 so that they must move together. The cord 9 is loopedupon this wheel and fastened thereto-g at a point on the circumference thereof; When the cord is pulled the top bar 3 is rotated by means of the wheel 26, and through the bands 8, the planes of the slats E and bar I are shifted.

and the top of the angle pieceZ'I extends outward from this plate and lies just under the edge 28. A horizontal slot'is thus formed to receive the bent-over upper edge of the angle piece It, which pivotally supports the rocker 29 and the grooved wheel 26. The edge 28 may be indented at one or more points 30 to make the edge 28 and angle piece grip the edge 29 of the part it tightly. The same parts and the same arrangement is utilized with the plate 4 to support the angle piece is which carries the hearing I? and plate l8 for the trunnion Ha.

The bracket plates 4 and have holes 3! for fastening devices to hold them in position. They may be disposed fiat against the inner side faces of the window casing; or against the faces of the window casings which are parallel to the plane of the window opening. In the latter case, the plates will project away from thecasings, and be perpendicular to the walls of the room con- 4 32 makes contact with the cover strip and the end 32' of this flange goes under the strip. As the section is pushed behind the downturned projection l5, ribs or projections 21a on the engaging faces of this section and the projection [6" ensure a good fit of the two, so that the section 40 cannot be pulled out.

In Figure 10, the plate for the end of the top bar with the trunnion Ila is shown in part at 4", as seen from above, with the'fixed tongue 41). The flange 32a is hinged to the plate 4 and can be swung to the right to permit the adjacent end of the cover strip 33 to engage the lug lb. The

taining the window. Flanges 33 at one edge- The edges of each plate which are opposite to the flanges 33 present flanges 32, the lower ends of which are bent over, as indicated at 32. Cut from each plate and bent out at a right angle to the face thereof is a tongue, or lug ii). Between the flange 32 and the lug 4b of each bracket is inserted a strip, not shown, for covering the top of the blind and the bar 3, with the plates 4% and 5 affixed in position in either way above described. This strip rests at its ends on the inturned end 32 of the flange 32.

- In Figures 5, 6 and '7 the rocker 23 is omitted, and the wheel 25a serves the additional purpose of a rocker. The angle plate or member lfia is bent in the reverse direction at the top; that is away from the plate 5, so that the vertical web of this part lies closer to the plate 5. The upper web of the part I311 extends away from the plate 5 and is then reversed to form a channel 28a. One side of this channel is fitted between the top edge of the plate 5 and the top of the angle piece or part 21. The grooved wheel 25a has recesses in its face and the key projection on the section l2 of the barhas two prongs to enter the recesses I90 at each side of the pivot stud 25. The wheel has recesses 34 on its face, and the lower end of the part Hill has a catch 35 with a projection 36, the catch being resilient and set to force the projection into the notches. This catch is afiixed to the part [6a at its lower end. The catch holds the wheel and the bar 3 with the slats 5 in adjusted position.

The modification of Figures 8 and 9 show bracket plate 4' with a projection H5" at its upper edge, bent down close to the face of the plate 4'. The lower edge of the projection I5 is turned outward, and carries the bearing H. On one edge of the plate 4 is the short flange 33 as before. Onthe opposite edge is a pivoted sectionr4c pivoted to the plate 4 at 31, near the lower corner. This section carries on its outer edges a flange 32 with inturned end 32', and has a notch or recess 3'! on its inner edge above the pivot 31 'to clear the cut-out tongue 4b on the plate 4'. When the plate 4 is secured 'to the inner face of the window opening, as shown in Figure l, the section 40 can be swung outward toward the observer. This enables the cover strip for the top bar to be inserted between the flange 32 and the tongue 4bof theplate5 first, and

the other end to be more easily mounted at the bracket plate 4. The other end of the cover strip, after the section to is rotated inward away from the window casing, or to the right in Figure 8, is held against the lug 4b. The section 4c is then pushed towards the plate 4' till the flange hinge as indicated at 32 may include a pintle 4" and urge the flange towards the lug 4b. This plate can be attached to the face of the window casing parallel with the inner surface of the wall when the blind cannot be mounted as in Figure l. The end of the tongue 4b may be bent over to enter a recess in the strip 38.
